4. Obtain Access Token

Use appid and appsecert to obtain access token,

Interface is

https://api.weixin.qq.com/cgi-bi... mp;secret=APPSECRET

The program is implemented as follows

$appid = ""; 
$appsecret = ""; 
$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$appid&secret=$appsecret"; 
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
$output = curl_exec($ch); 
curl_close($ch); 
$jsoninfo = json_decode($output, true); 
$access_token = $jsoninfo["access_token"];
Copy after login

You can also splice the address directly in the browser address bar. After execution, you will get the following data

Copy code The code is as follows:

{"access_token" :"N2L7KXa084WvelONYjkJ_traBMCCvy_UKmpUUzlrQ0EA2yNp3Iz6eSUrRG0bhaR_viswd50vDuPkY5nG43d1gbm-olT2KRMxOsVE08RfeD9lvK9lMguNG9kpIkKGZEjIf8Jv2m9fFhf8bnNa-yQH 3g",

Copy code The code is as follows:

"expires_in":7200}

The parameter description is as follows

is the access token.

Or use the official interface

DebuggingTools, the address is: https://mp.weixin.qq.com/debug/cgi-bin/ apiinfo?t=index&type=%E8%87%AA%E5%AE%9A%E4%B9%89%E8%8F%9C%E5%8D%95&
form=%E8%87% AA%E5%AE%9A%E4%B9%89%E8%8F%9C%E5%8D%95%E5%88%9B%E5%BB%BA%E6%8E%A5%E5%8F%A3% 20/menu/create

Use the web debugging tool to debug the custom menu interface

Click to check the problem and get

In this way, you also get the access token

5. Organize the menu content

Currently, the custom menu includes up to 3 first-level menus, each one The first-level menu contains up to 5

secondary menus. The first-level menu can contain up to 4 Chinese characters, and the second-level menu can contain up to 7 Chinese characters. The extra parts will be replaced by "...". Please note that after creating a custom menu, it will take 24 hours for the WeChat client to display it due to the WeChat client's caching. It is recommended that when testing, you can try to unfollow the public account and follow it again, and you can see the effect after creation.

Currently, the custom menu interface can implement two types of

buttons, as follows:

click：
用户点击click类型按钮后，微信服务器会通过消息接口推送消息类型为event 的结构给开发者（参考消息接口指南），并且带上按钮中开发者填写的key值，开发者可以通过自定义的key值与用户进行交互；
view：
用户点击view类型按钮后，微信客户端将会打开开发者在按钮中填写的url值 （即网页链接），达到打开网页的目的，建议与网页授权获取用户基本信息接口结合，获得用户的登入个人信息。

接口调用请求说明

请求示例

{ 
 "button":[ 
  {  
   "type":"click", 
   "name":"今日歌曲", 
   "key":"V1001_TODAY_MUSIC" 
  }, 
  { 
   "type":"click", 
   "name":"歌手简介", 
   "key":"V1001_TODAY_SINGER" 
  }, 
  { 
   "name":"菜单", 
   "sub_button":[ 
   {  
    "type":"view", 
    "name":"搜索", 
    "url":"http://www.soso.com/" 
   }, 
   { 
    "type":"view", 
    "name":"视频", 
    "url":"http://v.qq.com/" 
   }, 
   { 
    "type":"click", 
    "name":"赞一下我们", 
    "key":"V1001_GOOD" 
   }] 
  }] 
}
Copy after login

参数说明

返回结果

正确时的返回JSON数据包如下：

{"errcode":0,"errmsg":"ok"}

错误时的返回JSON数据包如下（示例为无效菜单名长度）：

{"errcode":40018,"errmsg":"invalid button name size"}

六、提交菜单内容给服务器

菜单的JSON结构为

{"button": [{"name":"天气预报","sub_button":[{"type":"click","name":"北京天气","key":"天气北 京"}, 
{"type":"click","name":"上海天气","key":"天气上海"}, 
{"type":"click","name":" 广州天气","key":"天气广州"},{"type":"click","name":"深圳天气","key":"天气深圳"}, 
{"type":"view","name":"本地天气","url":"http://m.hao123.com/a/tianqi"}]}, 
{"name":"方倍工作室","sub_button":[{"type":"click","name":"公司简 介","key":"company"}, 
{"type":"click","name":"趣味游戏","key":"游戏"}, {"type":"click","name":"讲个笑话","key":"笑话"}]}]}
Copy after login

将以下代码保存为menu.php，并且在浏览器中运行该文件（比如 http://127.0.0.1/menu.php），将直接向微信服务器提交菜单

php 
 
$access_token = ""; 
 
$jsonmenu = '{ 
  "button":[ 
  { 
   "name":"天气预报", 
   "sub_button":[ 
   { 
    "type":"click", 
    "name":"北京天气", 
    "key":"天气北京" 
   }, 
   { 
    "type":"click", 
    "name":"上海天气", 
    "key":"天气上海" 
   }, 
   { 
    "type":"click", 
    "name":"广州天气", 
    "key":"天气广州" 
   }, 
   { 
    "type":"click", 
    "name":"深圳天气", 
    "key":"天气深圳" 
   }, 
   { 
    "type":"view", 
    "name":"本地天气", 
    "url":"http://m.hao123.com/a/tianqi" 
   }] 
  
 
  }, 
  { 
   "name":"瑞雪", 
   "sub_button":[ 
   { 
    "type":"click", 
    "name":"公司简介", 
    "key":"company" 
   }, 
   { 
    "type":"click", 
    "name":"趣味游戏", 
    "key":"游戏" 
   }, 
   { 
    "type":"click", 
    "name":"讲个笑话", 
    "key":"笑话" 
   }] 
  
 
  }] 
}'; 
 
 
$url = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=".$access_token; 
$result = https_request($url, $jsonmenu); 
var_dump($result); 
 
function https_request($url,$data = null){ 
 $curl = curl_init(); 
 curl_setopt($curl, CURLOPT_URL, $url); 
 curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE); 
 curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE); 
 if (!empty($data)){ 
  curl_setopt($curl, CURLOPT_POST, 1); 
  curl_setopt($curl, CURLOPT_POSTFIELDS, $data); 
 } 
 curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); 
 $output = curl_exec($curl); 
 curl_close($curl); 
 return $output; 
}
?>

七、响应菜单点击事件

在消息接口中处理event事件,其中的click代表菜单点击,通过响应菜单结构中的key值回应消息，view事件无须响应，将直接跳转过去

define("TOKEN", "weixin"); 
 
$wechatObj = new wechatCallbackapiTest(); 
if (!isset($_GET['echostr'])) { 
  $wechatObj->responseMsg(); 
}else{ 
  $wechatObj->valid(); 
} 
 
class wechatCallbackapiTest 
{ 
  public function valid() 
  { 
    $echoStr = $_GET["echostr"]; 
    if($this->checkSignature()){ 
      echo $echoStr; 
      exit; 
    } 
 } 
 
  private function checkSignature() 
  { 
    $signature = $_GET["signature"]; 
   $timestamp = $_GET["timestamp"]; 
    $nonce = $_GET["nonce"]; 
 
   $token = TOKEN; 
    $tmpArr = array($token, $timestamp, $nonce); 
    sort($tmpArr); 
    $tmpStr = implode( $tmpArr ); 
    $tmpStr = sha1( $tmpStr ); 
 
    if( $tmpStr == $signature ){ 
      return true; 
    }else{ 
      return false; 
    } 
  } 
 
  public function responseMsg() 
  { 
    $postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; 
    if (!empty($postStr)){ 
      $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); 
    $RX_TYPE = trim($postObj->MsgType); 
 
     switch ($RX_TYPE) 
      { 
        case "text": 
          $resultStr = $this->receiveText($postObj); 
          break; 
        case "event": 
         $resultStr = $this->receiveEvent($postObj); 
          break; 
        default: 
          $resultStr = ""; 
         break; 
      } 
      echo $resultStr; 
    }else { 
      echo ""; 
     exit; 
    } 
  } 
 
  private function receiveText($object) 
  { 
    $funcFlag = 0; 
    $contentStr = "你发送的内容为：".$object->Content; 
    $resultStr = $this->transmitText($object, $contentStr, $funcFlag); 
    return $resultStr; 
  } 
   
  private function receiveEvent($object) 
  { 
    $contentStr = ""; 
    switch ($object->Event) 
    { 
      case "subscribe": 
        $contentStr = "欢迎洋洋博客"; 
      case "unsubscribe": 
        break; 
      case "CLICK": 
        switch ($object->EventKey) 
        { 
          case "company": 
            $contentStr[] = array("Title" =>"公司简介",  
            "Description" =>"洋洋的博客",  
            "PicUrl" =>"http://discuz.comli.com/weixin/weather/icon/cartoon.jpg",  
            "Url" =>"weixin://addfriend/pondbaystudio"); 
            break; 
          default: 
            $contentStr[] = array("Title" =>"默认菜单回复",  
            "Description" =>"您正在使用的是<span style="font-family: Arial, Helvetica, sans-serif;">洋洋的博客</span><span style="font-family: Arial, Helvetica, sans-serif;">", </span> 
            "PicUrl" =>"http://discuz.comli.com/weixin/weather/icon/cartoon.jpg",  
            "Url" =>"weixin://addfriend/pondbaystudio"); 
            break; 
        } 
        break; 
      default: 
        break;    
 
    } 
    if (is_array($contentStr)){ 
      $resultStr = $this->transmitNews($object, $contentStr); 
    }else{ 
      $resultStr = $this->transmitText($object, $contentStr); 
   } 
    return $resultStr; 
  } 
 
  private function transmitText($object, $content, $funcFlag = 0) 
  { 
    $textTpl = "<xml> 
<ToUserName><![CDATA[%s]]></ToUserName> 
<FromUserName><![CDATA[%s]]></FromUserName> 
<CreateTime>%s</CreateTime> 
<MsgType><![CDATA[text]]></MsgType> 
<Content><![CDATA[%s]]></Content> 
<FuncFlag>%d</FuncFlag> 
</xml>"; 
    $resultStr = sprintf($textTpl, $object->FromUserName, $object->ToUserName, time(), $content, $funcFlag); 
    return $resultStr; 
  } 
 
  private function transmitNews($object, $arr_item, $funcFlag = 0) 
  { 
    //首条标题28字，其他标题39字 
    if(!is_array($arr_item)) 
      return; 
 
    $itemTpl = "  <item> 
    <Title><![CDATA[%s]]></Title> 
    <Description><![CDATA[%s]]></Description> 
    <PicUrl><![CDATA[%s]]></PicUrl> 
    <Url><![CDATA[%s]]></Url> 
  </item> 
"; 
    $item_str = ""; 
    foreach ($arr_item as $item) 
      $item_str .= sprintf($itemTpl, $item[&#39;Title&#39;], $item[&#39;Description&#39;], $item[&#39;PicUrl&#39;], $item[&#39;Url&#39;]); 
 
    $newsTpl = "<xml> 
<ToUserName><![CDATA[%s]]></ToUserName> 
<FromUserName><![CDATA[%s]]></FromUserName> 
<CreateTime>%s</CreateTime> 
<MsgType><![CDATA[news]]></MsgType> 
<Content><![CDATA[]]></Content> 
<ArticleCount>%s</ArticleCount> 
<Articles> 
$item_str</Articles> 
<FuncFlag>%s</FuncFlag> 
</xml>"; 
 
   $resultStr = sprintf($newsTpl, $object->FromUserName, $object->ToUserName, time(), count($arr_item), $funcFlag); 
    return $resultStr; 
  } 
} 
?>

八、菜单中获取OpenID

由于菜单中只能填写固定的url地址，对于想要菜单中获取用户的OpenID的情况，可以使用OAuth2.0授权的方式来实现。

URL中填写的地址为一个固定的回调地址。原理方法可以参考 微信公众平台开发(99) 自定义菜单获取OpenID

<?php 
/* 
  洋洋的博客 
*/ 
 
define("TOKEN", "weixin"); 
$wechatObj = new wechatCallbackapiTest(); 
if (isset($_GET[&#39;echostr&#39;])) { 
  $wechatObj->valid(); 
}else{ 
  $wechatObj->responseMsg(); 
} 
 
class wechatCallbackapiTest 
{ 
  public function valid() 
  { 
    $echoStr = $_GET["echostr"]; 
    if($this->checkSignature()){ 
      header(&#39;content-type:text&#39;); 
      echo $echoStr; 
      exit; 
    } 
  } 
 
  private function checkSignature() 
  { 
    $signature = $_GET["signature"]; 
    $timestamp = $_GET["timestamp"]; 
    $nonce = $_GET["nonce"]; 
 
    $token = TOKEN; 
    $tmpArr = array($token, $timestamp, $nonce); 
    sort($tmpArr, SORT_STRING); 
    $tmpStr = implode( $tmpArr ); 
    $tmpStr = sha1( $tmpStr ); 
 
    if( $tmpStr == $signature ){ 
      return true; 
    }else{ 
      return false; 
    } 
  } 
 
  public function responseMsg() 
  { 
    $postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; 
 
    if (!empty($postStr)){ 
      $postObj = simplexml_load_string($postStr, &#39;SimpleXMLElement&#39;, LIBXML_NOCDATA); 
      $fromUsername = $postObj->FromUserName; 
      $toUsername = $postObj->ToUserName; 
      $keyword = trim($postObj->Content); 
      $time = time(); 
      $textTpl = "<xml> 
            <ToUserName><![CDATA[%s]]></ToUserName> 
            <FromUserName><![CDATA[%s]]></FromUserName> 
            <CreateTime>%s</CreateTime> 
            <MsgType><![CDATA[%s]]></MsgType> 
            <Content><![CDATA[%s]]></Content> 
            <FuncFlag>0</FuncFlag> 
            </xml>"; 
      if($keyword == "?" || $keyword == "？") 
      { 
        $msgType = "text"; 
        $contentStr = &#39;当前时间是：&#39;.date("Y-m-d H:i:s",time()); 
        $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr); 
        echo $resultStr; 
      } 
    }else{ 
      echo ""; 
      exit; 
    } 
  } 
} 
?>
